Health.com: Home Remedies for Allergies: What Works?

HEPA Filters

High-efficiency particulate air (HEPA) filters ease symptoms by trapping allergens and other airborne irritants, such as pet dander and dust. Portable air cleaners equipped with HEPA filters can purify the air in bedrooms and other confined spaces, but whole-house systems that incorporate HEPA filters into your home's heating, ventilation, and air conditioning (HVAC) system are generally more effective.

Air conditioners and dehumidifiers also can help clean air, Dr. Graham says. They remove moisture from the air and floor, which will curb the growth of the mold and mildew that can worsen allergies.
